Sorry this took awhile. I've got 8 absolute banger videos I'm currently working on through April 2021 but it turns out the Rona slows things down a bit. They will be worth the wait! For updates, follow me on social stuff @MarkRober.

All your experimentations are flawed..... The previous one with just human blood couldn't be enough. It's a combo, sharks are smart, sharks will evaluate the blood + something moving on the board or in the water, they detect vibrations and also electric signals from the human body.......... Your new experimentation doesn't make sense either... Obviously sharks will choose to go towards a more familiar blood. Its what they know the most, they are conditionned by it. It absolutely does not mean that sharks would not go in numbers towards human blood if it was the only choice. It's all about the number of choices offered and the natural instinct, the need to feed. In real life you would not have these choices so sharks would certainly come to pay a visit. In the end your experimentations prove nothing are useless....sorry... But the videos were cool for the entertainment.....
